. Applicationi'November 30,1932, Serial No. 645,055 Y 2 Claims(019123-190) This invention relates to an improved revoluble valve formultiple cylinder internal-combustion engines thepurpose being toprovide a valve of this character capable of operative association-inconnection with two cylinders, making it possible to use a single valveto cooperate with the intakes and exhaust ports of two-cylinders.

Another purpose is to provide, in'an engine of this kind a valveincluding apartition therein so arranged as to separate two ports formedinthe valvein order to so alternately register with the ports of thecombustion chambers of the cylinders as to. first permit of intake ofa'charge and then permit of exhaust of the utilized gases, the crankshaft of the engine being so geared with a shaft (which is sooperatively connected with the revoluble valve) as todrive theshaft at aratio of 2' to -1, namely if two revolutions of the crank shaft willcause one revolution of said shaft which in turn operates the valve.

Another purpose is to provide a valve of this kind inassociation with aninternal combustion engine, preferably of the two cylinder type, havingannular grooves in the exteriorsurface of the valve above and below theports, with inclined grooves above and below the'first grooves, whichpermit lubricant to feed to the surface of-the valve, and against theinterior'wall of the valve cylinder, together with sealing means to sealthe oil and prevent end play.

It is to beunderstood that the particulars herein given are in no waylimitative, and that while still keeping within the scope of theinvention,

' any desired modifications of details and proportions may be made inthe construction of the appliance according to circumstances.

The invention comprises further features and combination of parts to behereinafter set forth, shown in the drawings and claimed.

In the drawings: I

Figure 1 is a vertical sectional view through the improved engineshowing the valve applied.

Figure 2 is a sectional view on line 2-2 of Figure 1 showing thecylinders and their ports or passages connecting with the valvecylinder.

Figure 3 is a horizontal sectional view on line 3--3 of Figure 1.

Figure 4 is an enlarged detail view of the revoluble valve, with itswall broken away to show the partition between the two ports.

Figure 5 is a sectional view through the oiler.

Figure 6 is a view in front elevation of the cage which houses therevoluble valve, showing the guard 53 in dot and dash lines in order toexpose the parts behind it.

Referring to the drawings l identifies'the casing of the engine, whichcomprises the two cylinders 2 and the crank case 3, the cylinders beingbolted to the crank case at 4: Bolted at 5 to the crank case, is theusual oil pan 6, and mounted in bearings of the crank lcase'is a crankshaft 1, to which the usual connecting rods 8 are connected 'by means ofthe bolts 9 andcap plates I0. Connecting rods 8 are in turn pivoted tothe pins l' l which extend transversely of the pistons I2 which areprovided with the usualpiston'lings'lfiij The cylinders 2 are providedwith the usual water jackets/l4, while the head l5 (which is bolted atIE to thecylinders) is likewise provided with a water jacket ll, whichcommunicates with the jacket v I4 in'any well known conventional man- Es)PA ur ner. The interiors [8 of the cylinders merge into compressionchambers 19, in each of which the charge is compressed, on thecompressionstrolge of the piston. I

Carried by and forming part of the casing of the engine is a valvecasing 20, which hasa water "jacket 2!, which in turn communicates withthe water jacket I4 of the cylinders. Mounted in the valve casing is asingle revoluble valve 22, which. has in its Wall ports 23 and 24. Thevalve 22 is in the form of a hollow cylinder and is connected at 25 to avalve stem '26, -whichoperates through a guide 21 of the wall of anintake manifold 21a, which is bolted at 28 to the valve casing. Anexhaust manifold 29 is boltedat 30 to the valve casing 20. Adjacent theremote opposite ends of the valve 22 are oil rings 3l' and 32, theformer being in contact with the end of the exhaust manifold 29, whilethe latter is in contact with the end of the intake manifold 2100. Theseoil rings act to prevent lubri- I cant from reaching the interiors ofthe intake and exhaust manifolds.

The lower end of the cylindrical valve 22 is provided with intake ports33, which communicate with the intake manifold. The exterior surface ofthe valve is provided with annular oil grooves 34 and diagonallyinclined oil grooves 35, there being a suitable oiler 36 connected tothe valve casing 20 by means of the threaded a :worm 41 mounted on thecrank shaft.

result of the crankshaft revolving imparting motion from the worm- 41 tothe worm gear 46, hence imparting 'revoluble movement .to the with theports 40 and ll which communicate the compression chambers I9 with theinterior of theflvalve casing, thereby allowing alternate intake chargesto enter the compressionchambers on the suction strokes of the pistonsin the cylinders, as well as'permitting alternate exhaust of theutilized gases upon exhaust strokesof the pistons.

The valve stem 26 is connected at 42 to'a shaft 43 which passes througha'guidei'44, which is, anchored within and to the crank case 3, the

guide being adjustable for wear by means of the set screw 45. Mounted onthe lowerend of the shaft 43 is a worm gear 46, which meshes with- As avShaft 43 as well asthe valve stem 26,'thereby rotating the valve, sothatits ports may register with the compression chamber. The shaft 43 passesthrough a packing gland 48, and as previously stated is coupled at 42 tothe valve stem.

Thevalve stem'26 passes through a second packing gland. Suitable collars50 and 5| surround the shaft 43 and the valve stem 26 and act to retainthe packing in place, particularly so since a relatively strongexpansion spring 52 is .interposedbetween the two collars 50 and 51 andin surroundin'g relation with a. portion of the .s haft 43 and the valvestem 26 and-acting to spread the collars apart. In order to precludedust' and dirt or other foreign matter about where'the shaft 43 and thestem 26 are coupled 'andirom between the convolutionsof the spring,asuitable shield or guard 53 is positioned beween a part ofthe crankcaseand the intake manifold.

Located withinthe oil pan and bolted at 54 .to ther lower part of thecrank caseis an oil pump 55'having an oil line 56 passingthrough apacking plug 51 and in turn connected to the oiler1or lubricator 36 forthe valve.

From the foregoing it is obvious that an improved :revoluble valve isprovided for use in controlling alternate intake charges to the twocylinders as well as controlling alternate exhaust of the utilizedgases, it also being obvious how 'the engine and the valve operate.

The invention having been set forth,;what is claimed is:

1. The combination with an internal combusvalve having upper and lowerexhaust and intake chambers and provided with intake and exhaust portsalternately communicating the intake and exhaust chambers got the valvewith said combustion chambers, exhaust andintakepassages above and belowthe valve and communicating with the upper, and lower exhaust and.intake chambers of the valve, said stationary thrust bearing oil ringsbeing serviceable to prevent seepage of oilintothe exhaustand-=intakepassages and the. chambers, and means to rotate the valve. 7i

2. The combination with} an internal combusj tion engine including acasing having a crank case .and a multiple of cylinders including pi stons operable therein,. of -a cylindrical valve chamber formedin saidengine casing andhaving multiple combustion chambers connecting thecylinders'and the valve chamber, exhaust and intake. manifolds above andbelow and communicating with the valve chamber, upper and lowerstationary thrust bearing v oil rings in said valve chamber, acylindrical hollow revoluble valve in the valve chamber and serviceablebetween the stationary thrust bearing oil rings, said valve having upperand lower exhaust and intake chambers communicating with the ,ex-

haust and intake manifolds, said valve having intake and exhaust portscommunicating the intake and exhaust chambers of the valve alternativelywith the multiple combustion chambers, and means to rotate the valve. Ij
